GILBERT G. SGHOW, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 162,197, dated April 20, 1875; application filed June 18, 1874.

To all whom it may concern:

Be it known that I, GILBERT C. SOHOW, of the city of Chicago, in the county of (look and State of Illinois, have invented a certain new and useful Improvement in Oar-Couplings; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawing, which forms a part of this specification, and on which Figure 1 is a top View. Fig. 2 is a longitudinal vertical section, in the plane indicated by the line 00 .r in Fig.1. Fig. 3 is a perspective view of the lock or swing bolt used in combination with my invention, and Fig. 4, represents a view or plan of the under side of the top casting of a draw-head having my improvement.

bimilar letters of reference indicate corresponding parts in all the figures.

My invention relates to that class of carcouplings in which the coupling is effected automatically by a lock swingbolt or levercatch, placed vertically within the link-receiving chamber in each draw-head; and it consists in so shaping the top casting of the draw-head that a projecting ridge or flange thereon will fit snugly into the link-receiving chamber in the under casting, thereby adding great strength and solidity to the draw-head, as hereinafter more fully set forth and explained.

A A denotes the draw-head, which is made in two pieces or castings, a top casting, A, and an under casting, A. The line y y in Fi 2 shows the plane connection of these two separate castings, which are held together by bolts or screws, in theusual manner. G is the lever-catch, which is pivoted at b in the top casting of the draw-head, and swings vertically through the slot a, Fig. l, in said casting. This slot is encircled, at its rear end within the draw-head, by a dowuwardprojecting horseshoe-formed flange, c, Fig. 4, which, when the top casting is placed in its proper position upon the under casting, fits snugly within the link-receiving chamber, thereby preventing lateral motion of that part of the draw-head which has the greatest strain to sustain. cl is a spring, secured on the top of the draw-head in such a manner as to press upon the top side 6 of the lever-catch (J, thio'igh the slot (0. The lower point fof the said lever-catch rests within a recess or catch socket, g, in the bottom of the link-receiving chamber, thereby preventing lateral motion of the catch. D is a chain, secured to the top of the levercatch in such a manner as to straddle the spring (I at h. This chain serves to raise the catch-lever 0 when it is desired to uncouple the cars. B denotes the link.

Having thus described my invention, I claim and desire to secure by Letters Patent- I11 a draw-head constructed of two parts, A A, stationary in their relation to each other, the horseshoe-formed brace or shoulder 0, cast in one piece with the top A, and projecting into a corresponding recess in the bottom part A, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in presence of two witnesses, this 18th day of March, A. I). 18745.
